CALCULATING-MACHINE.

To all 'whom it may concern."

B e it known that I, HYMAN ELI GOLDBERG, a cltizen of the United States,residing at Chicago, in the county of Cook and State of manyrespects-the same as the one shown in my application for patent filedSeptember 15, 1905, Serial Number 275,780. The di'fference between themachine there shown and the one here shown lies in the controllingdevice,- and in the present application I do not claim broadly acontrolling device capable of determining whether at any given point thetotalizer shall add or subtract or not operate,'.but the present claimsare to be construed as subject to the'ones made in the aforesaidprevious application.

In the former application the form of controlling device shown was a camand pin mechanism, and the pins were shown to be stationarywhile thecams moved relatively thereto. Also the pins were adjustable in theirholders and the adjustment of the pin determinedwhich of the threepossible results in the operation of the mechanism should occur.

The object of the present invention is to provide a stationary cam and atraveling pin, and also to provide means for facilitating the removaland substitution of different shaped cams; also to provide meanswhereby. cams embodying different combinations of acting surfaces may beemployed.

To illustrate my last object, suppose it be desired that a giventotalizer-shall add in the first column, subtract in the second and reamain idle in the third. These three conditions can be obtained in 'the'resent device by inserting a cam having sur acesarranged to produce thisparticular combination of actions. Suppose for another set of bills oraccounts, it should be i-desired that the same totalizer should subtractin the first column,

remain idle in the second column, and add in the third column. Thisdifferent combination of actions could in my present invention beobtainedby introducing a cam capa- 4 Specification of Letters Patent.Application filed December 22, 1205. Serial No. 292,932.

of actions, and as a result of this resent invention'the operator isable by se ecting the proper cam, to produce any particular cominationof actions that he desires.

I obtain my objects by the mechanism illustrated in the accompanyingdrawings, in which Figure 1 is a general front elevation of my inventionin-the form of a oulculating attachment to a typewriter.

This wheel is non-rotatable and is shown to be pinned to theaxle, whereas the intermediate wheels to the left thereof are rotatable.Fig. 16 is a sectional view taken on line 16-16, Fig. 13. Figs.17,18,.19and 20 are side views of component parts of the totalizer.

1 represents the framework of a typewriter having a laterally shiftablecarriage 2 and vertically movable keys 3. Such ones of said keys as arenumeral keys are connected by means of links 4, or otherwise, to anappropriate part of the valuating mechanism 5.

The precise construction of said valuating mechan sm is lmmatenal, itsfunction being ble of producing this particular combination zer suitable-similarly, shaft 12 has rigidly fixed thereon -to rotate as a singlepiece.

to drive gear wheel 6 different amounts, depending upon the value of thekey temporarily in'action. A suitable form of valuatbracket being boltedor otherwise secured to the frame-work 1.

From wheels 7 and 8 connections are provided for. rotating thesetting-wheel shafts l1 and 12; and in the construction hereillustrated, these connections comprise the miter gear wheels 13, 14,15, 16, 17 and 18, gear wheels 13 and 14 rotating as a single iece andoperating to drive the gear whee 15, which is rigidly affixed to shaft11. Gear Wheels 16 and 17 rotate as a single piece and operate to drivethe gear Wheel 18, which is rigidl affixed to shaft 12. The axes of whees 13, '14, 16 and 17 are stationar and in the present design arevertical, and said wheels are journaled in suitable bearings mounted onthe bracket 10. Shafts 11 and 12 have axes parallel to the path of thetraveling carriages 2, and in the present instance they are journaled inbearings 19 mounted on bracket 10. The shaft 11 has rigidl fixed thereona set of spur wheels 20, an

a set of spur wheels 21, said wheels being designed to operate theaccumulating wheels 22 of the totalizers. The arrangement is such thateach Wheel 20 is directly 0 posite to its respective wheel 21, but atsue]? a distance therefrom that a receiving wheel is never in mesh withboth operating wheels at once. It may be in mesh with either one or outof mesh with both. Shafts 11 and 12 rotate in opposite directions, andtherefore one Of them will cause the receiving wheels to rotate in onedirectionand the other in the opposite, direction. The totalizer hereshown is adapted'to add when operated in one direction and to subtractwhen operated in the opposite direction and although various types oftotalizers may be employed, for example, the one shown in the patentgranted to me October 20, 1903,'Serial No. 741,961, 'I have here "shownand will now describe the form of totalizer for which Letters-Patent No.782,604 were granted to me February 14, 1905.

Referring more particularly to Figs. 13 to 20, both inclusive, eachtotalizer comprises a shaft 23 non-rotatively mounted in the side,

walls or totalizer framework 24 and a plurality of sets or grousconsisting of five principal parts, name y: totalizing wheels 25,carrying pinions 26, accumulating wheels 22, above mentioned, epicyclicpinions 27 and the intermediate wheels 28. Wheels 22, 25 and 28 are allfreely rotatable about shaft 23 independently thereof, with theexception of wheel 28 located at the extreme right to correspond withthe units column. This wheel is rigidly fastened to shaft 23 b means ofa pin 28 (shown in Fig. 15) athough any other means may be substitutedfor holding it rigid and non-rotatable. The function of said wheel 28 isto formv the fixed basis of reference or foundation piece for themechanism from which the rotatable parts move their definite amounts. Ineach group of parts, 23 represents a supporting iece, whlch in thepresent instance, is diskike in form and is secured to shaft 23 by meansof a spline 23 Said supporting piece is provided at its left side with ahub 23, which is cylindrical and forms a bearing whereon theintermediate wheel 28 is freely rotatable. The pin 23 extends toward theleft from said supporting piece 23 and serves as an axle whereon thecarrying pinion 26 is freely rotatable. Said pinion has eight long andshort teeth alternating with each other for alternately being locked androtated by the totalizing wheels 25 in the manner hereinafter described.

The totalizing wheels 25 carry on their cylindrical peripheries twoseries of figures for visibly indicating the number set up, as usual inmechanisms of this class. Each series of figures runs from 0 to 9., thusmaking 20 figures whichv are consequentl of a circumference apart. Saidwhee s have formed upon their right portion an in '25 for locking thecarrying pinion 26, which constitutes a locking rlng. Each totalizingwheel has two slots or spaces 25 located diametrically opposite to eachother, each slot having a rojecting carrying tooth 25 on each sidetliereof for engaging the teeth on said carrying pinion. At the leftside of the totalizing wheel is an internal cylindrical surface or ring25 which is of greater diameter than ring 25 and is cut in the wheel forthe purpose of locking the short teeth on said carrying pinion. Theconstruction is such that the carrying teeth 25 of the wheel 25 willengage the short teeth of pimon 26 and rotate the same two steps or twospaces, after which the locking ring 25 will enter between two adjacentlong teeth on the pinion 26 and lock the same. During the rotation ofthe locking pinion the space 25 Wlll permit the rotation of the carryingplnion b receiving one of the long teeth thereo Thus when the totalizingwheel 25 is rotated, it will, twice during each complete rotation,impart a partial rotary movement to its carrymg pinion to carry thetens. in the present construction the totalizing Although wheel 25carries at two points and has two sets of figures, the fact that it isdouble is merely a matter of design and convenience in the constructionand operation. Each totalizing wheel 25 is supported by the contact ofits internal cylindrical surface or looking ring 25 upon the cylindricaledge ofthe sup orting piece 23*. Said wheel is thus free y rotatableindependently of piece 23* and remains at all times concentric withshaft 23.

' Theaccumulating wheels 22 are analogous to the receiving wheelsdescribed in my former patents Nos. 710,772 and 741,961 and in myaforesaid patent application in, that they are adapted to be rotateddifferent amounts for accumulating the digits. They are plainthirty-two-toothedspur gears having a comparatively large central aerture so that theymay set over and be free y rotatable upon the pointsof the teeth of the intermediate wheels 28. ,By preference, saidaccumulating wheels are narrow and their teeth project beyond thecircumference of the totalizing wheels 25, so that they may be engagedby the setting wheels 20 and 21. The totalizing-wheel 25 and suportingpiece 23 (shown at the extreme left of Fig. 15) are slightlymodified to illustrate the form which these parts will take to-impart aworkmanlike appearance to the highest or extreme left termination of thetotalizer. Extending toward the left from each accumulating-wheel 22 arethe pins 22 22 which constitute axles for the e icyclic pinions 27, 27;said pinions are free y rotatable upon said pins 22 and are epicyclic inthe sense of being rotatable upon an axis which is itself movable aboutanother center. They are designed to remain at all times in mesh withboth the intermediate-Wheel 28 and,the internal gear wheel 25 fortransmitting rotationfrom the former to the latter. Theyare plainspurpinions, and, in the present instance, have eight teeth which is thepro er number to cooperate with the forty-toot ed internal gear 25 andthe twenty-four toothed intermediate spur-wheel 28.. Although two eicyclic pinions 27 are here shown, one is t eoretically sufiicient fortransmitting motion to the two carrying Wheels. Two pinions cause themechanism to operate more smoothly.

Each intermediate-wheel 28 is a wide faced twenty-four toothed spur-gearhaving a full com lement of teeth, and when in position on t e hub 23 onthe iece 23, remains per- 'manently in mesh wit the carrying pinion 26,so that any rotation of said pinion will lmpart rotation, to saidintermediate-wheel. Said intermediate-wheel also remains permanently inmesh with the epicyclic imons 27 aforesaid, and the relationship of t eparts is such that the pinion 27 engages the left portion of wheel 28,while the pinion 26 engages the right portion thereof, and theaccumulatin the present construction, is g nd of the cir- .tions.

ing-Wheels 22 occupy an intermediate position. The purpose of saidintermediatewheels is to transmit rotation from the carrying pinions 26to the epicyclic pinions 27, and through said epicyclic pinions to theaccumulating-wheels 22.

To illustrate the operation of the totalizer, suppose that some oneintermediate-Wheel 28 is temporarily held fast, and that its ac-.cumulating-wheel is rotated one step, which,

cumference. By means of its epicyclic pinion 27 it will move thetotalizing-wheel at the left from one figure to another on thetotalizing-wheel. If the accumulatin -wheel 22 89 had been rotatedseveral steps, t en the totalizing wheel 25 would have been rotated justas many figure-distances. The figures are thus accumulated upon thetotalizingwheel. Again, suppose the accumulating- 5 wheel 22 to betemporarily held fast and the totalizing-wheel 25 at its right to berotated. As long as some part of the locking ring 25? on saidtotalizing-wheel is lying between two of the longer teeth of thecarrying pinion 26, no rotationis imparted by said totalizing wheel tosaid pinion. But as soon as the space or cut 25- and the carrying teeth25 pass said pinion they rotate it two steps or spaces, and immediatelylock it a ain. This occurs when the figures 0 and 9 are interchanged atthe reading line. The carrying pinions 26 rotate the intermediate wheel28 an equal amount, and wheel 28 rotates the epicyclic pinion 27 whichrotates the Wheel 25 next to the left an'equal amount in the samedirection as wheel 25 to the right is rotated. Thus the tens arecarried. It is evi dent, therefore, that themechanism is able to carrythe tens when an accumulating wheel remains motionless. It is true,therefore, that the numbers may be accumulatedon the totalizing wheelsindependently of the carrying-wheels, and the tens may be carriedindependently of the accumulating-wheels. Each action is inde endent ofthe other, and the actions may tal e place either separately orsimultaneously. In either case, the final result will be the same-thatis, the algebraic sum of the accumulating and carryin ac- 11 Therefore,if the totalizing-whee s 25 show 467 for example, and it is desired toadd 789 the hundreds, tens and units accumulating-wheels may be rotatedseven, eight, and nine ste s, respectively, at one and 120 the sametime, an the total 1256 will 'instantly appear and the mechanism will beready for t e next number without any further re-setting or adjustment.In other words, the mechanism is so universal in its 125 operation thatthe accumulating-wheels 22 will each have their proper influence uponthe mechanism, no matter whether they be rotated all at once or singlyin their proper denominational order, or in any other order. 13

Havin thus described the totalizer here indicate which is one of theforms suitable for use in the present machine, I will now continue thedescription of the parts which operate'the totalizer. Theoperating-wheels 20 and 21, hereinabove mentioned, which may be termedthe"set ting-wheels, occur setting-wheel to add, or'with the oppositeone to subtract, or with neither to not operate. In addition to itsbodily movement transverse to the axes of the setting-wheels, thetotalizer shifts or travels laterally with the carriage 2, and the meansfor accomplishing these movements will now be described.

A bar or slide 29 is slidingly mounted upon the stationary guide-bar 30in such manner that it may travel in a direction parallel to the axes ofthe setting-wheels 20, 21. In the preferred form, the traveling motionof the carriage is imparted directly to the slide 29 by means of asocket or keeper 31 fastened to said slide, and adapted to engage thearm 32 fastened to the carriage. Rigidly fastened to the slide 29,preferably by means of brackets 33 thereon, is a bar 34 which liesparallel to the axes of the setting-wheels, and is adapted to supportone or more totalizers. Said totalizers are so mounted upon said bar asto travel with the same, but be independently movable transversely tothe settingwheel axes, in order to provide means whereb the totalizermay be adjusted lengthwise of bar 34. -A clip 35 is mounted on said barand so constructed as to straddle the totalizer without interfering withits transverse movement, and, at the same time, the clip preventslateral movement. The clip may e set in any desired position by means ofa set-screw, or otherwise. It is obvious that great variation may bemade in the means or adjustably holding the totalizers upon theirsupporting bar, the specific form of means belng immaterial. In thepreferred construction, bar 34 is cylindrical, and located approximatelymidway between shafts 11 and 12, somewhat above them, so that thetotalizers may be swung from side to side upon'the bar as'a pivot. Thecontrollingmeans here shown for causing the establishment ordisestablishment of connection between the totalizers and the actuatingmeans is a cam device, but is different from the one shown in myaforesaid application Serial Number 275,780, in that the cam track isstationary and the operating pin travels in unison with the travelingpart of the machine.

There are other features of novelty in con nection with the presentcontrolling means, which will now be described. In this device,ostponing for the resent consideration of P igs. 11 and 12 the (fiawin swhich are hereafter referred to) each tota izer has a pin 36 which isadapted to be acted upon by the cam surfaces of the cam tracks 37. Thecam surfaces 37*, 37 and 37 (Fig. 7) are so related with reference toeach other and to the other parts of the machine that when a pin 36 isin contact with surfaces 37 the totalizer will mesh with thesetting-Wheel on one of the setting shafts, when said pin is in contactwith the surfaces 37, said totalizing wheels will mesh with the settingwheel upon the other of said shafts; and when said pin isin contact withthe surfaces 37*, said totalizing wheels will remain out of mesh withsaid wheels; in other words, one of said cam surfaces will cause thetotalizer to add, and another to subtract, and'another to hold thetotalizer in non-active position. The different cam surfaces 37, 37 and37 are arallel with the line of travel of the totalizer, but thedifferent surfaces connect one with the other by means of beveled oroblique surfaces 37 so that the cam-pin 36 may be passed from onesurface to another as the totalizer travels alon the cam track. Theactual construction 0 the cam and pin may be considerably varied withoutdeparting from the s irit of this invention, for example they may beformed in the manner shown in Figs. 11 or 12. In Fig. 11 the camsurfaces instead of being sunk below the up er surface of the cam orstrip 37 are raised above it, forming the cam 37. The cam pin 36 isbifurcated and may with propriety be supplied with'antifriction rollers36". The operation will be the same as in the previous y described formof controllingdevice. The pin may also be double and integral with oneof the walls 24 of the totalizer as shown in Fig. 12. I In this case thewall has a notch 24 with actin surfaces 24 24 on each side thereof whichvirtually constitute pins.

In the design of the machine here illustrated four separate cam-tracksare shown which renders. it ossible for four different totalizers eachto ave their own individual cam-tracks. It is obvious, however, that thenumber of cam tracks is immaterial, and it is also obvious that morethan one totalizer might be operated from a single cam t ack. In orderthat the different totalizers may be controlled by their own cam tracks,the pins 36 occupy a difierent relative position upon each of thetotalizers. For example, the totalizer adapted to be operated by thecamtrack nearest to the front has its in nearest to the front of thetotalizer, an the other totalizers have their cam-pins farther back,

talizer action and seeing that each depending upon which one of thecam-tracks is intended to operate them.

The cam tracks here shown are in the form of bars or stri s havinggrooves or channels whose latera surfaces constitute the cam-surfaces,and it is evident that a great number of different combinations ofarrangement of cam-surfaces may be made. For instance, a strip or barmay be so constructed that it will cause its totalizer to add whenopposite the first pair of setting wheels, subtract when opposite thesecond pair, and remain idle when opposite the third air, or may causethe totalizer to subtract W en opposite the first pair of settingwheels, add when 0 posite to the second pair, and remain i e whenopposite .to the third pair. In actual practice an o erator will selecta cam strip or bar, which iias the desired combination'of cam surfaces,and will continue to'use this strip or bar as long as it serves hispurpose by producing the successive actions desired for his bill oraccount. But the o erator will change the strip or bar and substituteanother, as soon as he Wishes to produce a new kind of bill or account.As a matter of fact, in the ordinary commercial, banking, and brokeragehouses, the same form of bill or account is repeated over and over, andtherefore the substitution of new cam strips or bars will not befrequent, but in order that a cam strip or bar having the desiredcombination may be readily substituted when occasion demand, thestripsare made removable by mounting them within the retaining walls or posts38 mounted upon the bracket 10. The distance between the brackets deends upon the number of different strips w ich are to be in the machineat any one time, and new strips may be substituted by merely slippingthe old strip out and the new one in. This form of controlling-cam has acertain advantage in that a whole new combination of results may beobtained by merely slipping in or adjusting to position a single stripor bar; and as the combination is permanent, or as it were, stereotyped,in any given cam strip or'bar, the operator is relieved of the necessityof adjust ing a number .of separate pieces for each toone. of thesepieces is in its correct position before he operates the machine.

It will be noticed that there is no particular relation between thelength of the cams and the width of the totalizers. It is possible tomake the cams longer or shorter than the width of the correspondingtotalizer. By making a cam shorter than the width of the correspondingtotalizer, columns printed closely together may be summed and the amountregistered on the totalizer, although the total of the items in eachcolumn may be considerably wider than the width allowed for the largestitem on the paper. or

by Letters Patent, is

ing

example, let it be assumed that a machine is wanted for summing twocolumns of items which are always less than a dollar in. amount. Let itbe assumed that for some reason the two columns are to belocated side byside on the pa er without any space between them. It is o vious thatordinarily it will require three or four figures to repre sent the totalof each of these colunms, and such totals cannot of course be exhibitedon a totalizer which has but two figure wheels, so for such a case,totalizers each having three or four or more figure wheels will beemployed, and the cams will cause the first totalizer to be operated inits dimes and cents colunms and immediately thereafter the secondtotalizer to be operated in its dimes and cents columns.
